CROSS-REFERENCE TO RELATED APPLICATIONS

This Nonprovisional patent application claims priority to ProvisionalPatent Application No. 62/292,977, filed Feb. 9, 2016, which is herebyincorporated by reference in its entirety.

FIELD OF THE INVENTION

The present disclosure relates to a charcoal grill apparatus, and morespecifically to a fast-starting and portable charcoal grill apparatus.

BACKGROUND OF THE INVENTION

Urban dwellers who wish to grill using charcoal often do not have thespace to store and operate a full size charcoal grill. Smaller grills,while more portable, require additional accessories such as a chimneystarter or ignition fluid to help with igniting the charcoal. Ignitionfluid can negatively affect the taste of the food. Chimney starters,while chemical-free, can be almost as large as a compact grill itselfrendering it inconvenient for a solo operator to transport both thegrill and the chimney starter to and from the grilling site.

BRIEF SUMMARY OF THE INVENTION

The disclosed charcoal grill apparatus may function both as a portablechimney starter and a grill. The apparatus may, in embodiments, combinethe elements of a chimney starter and a grill in a compact form that iseasy to handle pre and post grilling. In its “chimney configuration”,the operator may fill the device with charcoal and ignite kindlingmaterial in a portion of the device underneath the charcoal. This allowsfor the “chimney effect” that may produce a rapid ignition of thecharcoal. After the charcoal is lit, the operator may configure thedevice into a “grill configuration” and may operate it as a grill. Thismay be accomplished by releasing and pulling down the hinged frontsidewall until it is level with the charcoal grate, revealing additionalsurface area to spread the charcoal.

A food-grilling grate may then be affixed several inches above thecharcoal surface. This two-in-one utility may eliminate the need forcharcoal lighting accessories or chemicals beyond basic paper forkindling.
